I have resisted getting an AR15 for years figuring that my Saiga .223 with it's AK type action was good enough. But somebody did offer me a complete AR with like 6 magazines, ammo, and case for a pistol I no longer wanted so I did the trade.

As a signal of my total submission I also ordered an upper in .300 Blackout.

Supposed to be delivered tomorrow. When the reloading dies arrive I do not know right now, Anybody got any good recipes for .300 Blackout with maybe 150 grain bullets using H414, BL-C(2), or H4895?
